The Cut Percentage table belongs to the aux limiter and only shows up when the limiter's Cut Type is set to Cut Off. Instead of cutting everything at one RPM, you set what percentage of firing events are cut, and that percentage can change across a range of conditions. It's an 8x8 table, so it can be mapped in 3D.
When you'd use it
A percentage cut is handy when the aux limiter is doing more than a simple rev limit, such as a basic launch control setup, where you want a softer cut in some conditions and a firmer one in others. It also changes the sound and feel of the limiter.
What to check
- The Cut Type really is Cut Off, or this table has no effect.
- Both axes use channels that make sense for the job.
- The switch or input in aux wiring activates the limiter when you expect.
- Logs show engine speed held where you want it at the aux RPM limit.
